Generative AI
I built an MCP server that lets AI agents extract structured product data from any URL - and it charges them $0.01 USDC per call, automatically, with no API key. The whole thing went from idea to public-on-npm in 36 hours. If you have Claude Desktop, Cursor, or Windsurf, you can install it right now: { "mcpServers": { "x402-extract": { "command": "npx", "args": [ "-y", "x402-extract-mcp" ], "en": { "BUYER_PRIVATE_KEY": "0x. " } } } } Restart your client.
